Abstract
The critical behavior of the s-state Ashkin-Teller-Potts model on a square lattice is studied for s=3, 4, and 5, using a variational renormalization-group transformation of the type introduced by Kadanoff. For the s=3 and s=4 models, the transformation correctly predicts a continuous phase transition. The calculated values of the critical exponents and the transition temperature are consistent with the results obtained from other approaches. For s=5, however, the transformation fails to detect the first-order transition that is known to occur.
